How we handle expansion joint sealing in Hampstead
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it, and we will confirm the choice in the quote. Site teams most often ask us about layers of sealant in a movement joint and weathered movement joint sealant that no longer flexes, across car park decks and ramps, cladding panel joints and blockwork control joints. A specialist sealant contractor works differently from a general builder: in Hampstead, that means joint design, primers and backing rod as standard.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Hampstead, as everywhere in London, access, loading and the ULEZ all come into the plan.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Inspect movement joints alongside other routine building checks
- Report split or peeling joint sealant early
- Keep scrapers and ploughs from dragging across joint sealant
- Reopen bays and walkways only after the stated cure time
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, ring 01277 525 020 or use the quote form with photographs.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Expansion joint sealing around Hampstead: how the place shapes the job
The 3 miles around Hampstead take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards normally have to keep running, which is why we work a few bays at a time.

On a site such as The Quadrant Business Centre (1.5 miles south-west of Hampstead), the movement joints are in car park slabs, paving and building elevations.

Signs you need expansion joint sealing in Hampstead
Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.
Most enquiries start with something like this:
- Sealant pulling off the joint face
- Water dripping through deck or ramp joints
- Joints packed with grit and debris
- Arrises breaking up along floor joints
Another example is Regis Road Business Park, 1.5 miles to the east of Hampstead, where floors and yards would be done in stages around the occupiers.
What your quote should include
- The terms of the workmanship guarantee
- Do they follow the manufacturer’s priming guidance?
- Can the work be phased to keep areas open?
- How the existing material will be dealt with
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
Questions we’re asked in Hampstead
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.
Is hospital work, at somewhere like Royal Free Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
What happens if it rains on the day?
Sealant needs a dry joint and a temperature within the product’s range. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.
How long does movement joint sealing take?
Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. We confirm the timescale with the quote, including any phasing.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Diagnose, treat, sign off
Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a job in Hampstead, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed
- Agree which areas must stay open
